Safety Information
Placement
Apart from the valves, which, by their very nature, are designed to run hot, the DAC-10 / DAC-
10 DSD is relatively cool running and operates well below the maximum allowed temperature
for consumer audio.
It should be positioned so as to allow free airflow around it and not placed on top of other
equipment – particularly Class A amplifiers, which run hot.
Possible vibrations should be minimised as far as possible. For example, the DAC-10 / DAC-10
DSD must not be placed on top of speakers. Ideally, the unit should be placed in line with (or
slightly behind) the plane of your speakers and additional benefits may be gained by placing it
on a good quality isolation platform.
Cleaning the unit.
Always disconnect the power cord from the mains socket when cleaning or performing other
maintenance.
Tube replacement.
The front pair of matched valves can be replaced with the same type allowing users to tune the
sound slightly. Please contact VAD or your dealer for advice on replacements. Valve codes
6SN7, 6N8S, 1578, ECC32, CV1988, 6SN7GT, 5692, CV181 or other direct equivalent to 6SN7 are
compatible. Please note: The protective cover will not fit over the taller CV181 valves.
Use of any other valve type will damage the circuit and invalidate the warranty. In case of
"valve rolling", the use of octal valve socket savers is strongly advisable, as any damage to the
valve sockets caused by "valve rolling" is not covered by the warranty.
The matched pair of 6N6P should only be replaced with the same type or 6N30P.
The pair of CV574 rectifier valves can be replaced with the same type or 6C5S, EZ35 or 6X5GT
equivalents.
Only a VAD authorised service agent should replace the internal ECC84 HF valve.
